To all whom it may concern:

Be it known that I, CHARL E8 W. Jaroox, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Dish-Washing Machines, of which the following is a s ecification.

My mvention relates to machines for washing dishes, and particularly to machines provided with a plurality of tanks into which the basket containing the dishes is set, there being provided means for forcing currents of water through the basket and around the dishes contained therein.

One of the main objects of m invention is to provide a dish-washing mac ine driven by an extremely simple steam motor connected with the' shaft or shafts thereof.

A further object is to provide means for causing a proper circulation of water within the washing tanks.

A third object is to provide means for carrying 08 the water, for heating the water within t tanks and for cleaning out the' discharge pipe leading from the tanks.

. In the drawin Figure 1, is a lon 'tudinal section of an embodiment of my iiivention. Fig. 2, is a plan view. Fig. 3, is a detail plan view of one tank. Fig. 4, is a detail lan view of one of the driving wheels, and ig. 5, is a side elevation of the cage surrounding the rotating blades.

The tanks A, B, C are arranged in series, the tanks A and B being provided with means whereby water may be violently c roulated or agitated about the dishes held therein, while tank C is a rinsing tank and is not provided with any means for a Ttating the water. Through the bottom 0 each tank A or B projects a shaft D- driven by a motor at its lower end and carryin blades E and F, The motor which I have s 'own and which I prefer to'use' is a simple steam. turbine wheel- I fast on the lower end of the shaft 1) and contained within a casing H. The turbine wheel may be of any suitable construction and is provided with a steam pipe I leading from any suitable source of steam and adapt d at its en to pnpeet a je of steam upon the cur d blade Q the urbinp, so as to rotate the same. the casing H a plpg 1' leads the exhaus =4 to the turbine wheel G. whose blades are oppositely directed to the blades of the taribine G. From thence thesteam may be led out by any suitable exhaust or led by a pipe 1- into the tanks. While I have shown a pipe I as leading from the casing of the turbine G, I of course may take th itfihtm direct from the pipe I or use separate P1 S to supgy steam to the turblne. The an blades are located Just above tbebotton; of the tanks A, B, and the like blades E in the tank B are reversely owed to blades E in tank A. Located abovwth blades E and P6313125 upon upward y p. 79- jecting lugs J form on the bot om of each tank is a table or plate K hav ng an open; through its center through w eh the aha D passes Above the plate K the shaft provided with the serew b ad .F. hes a e mclined in such mann r tha they act as screws to draw wa er downward nto the space surm ndmg the shaf 1. nd force towards. the blades B so hat they may throw t outward as sh wn n Fig;

As shown in F a- 3, the deflectmg lugs J project upwardly from the bottom of the ank n such positi n tha the eurrents o water when thrown outward by the blades E will strike against the faces of the lugs and be deflected towards the corners of the tank.

At he ners of the tanks are pro id dthe vertical partition plates L which are .mlfifid. above the tank bottom at their lower as at Z, and are also prov1ded, wlth an opening t ab u hei mlddl It will be seen from the arrows n F g, 1 h th wa e c du wa d by th blade E passes through the openings 1, upward to the open ngs 1 where 1t 1. dr wn inward in ontact wi h th dish s in he mid le of t baske Wat r is als arr ed o er he topof the artition L as sho n by he a rows in Fig- L and n ntac ith the dlshes 1n the p part of the basket.

shafts D is a cage M shown in detail in Fig.

this cage being formed o s r ps of metal.

net ing ppr ximately square in plan a d has a central opening winch surrounds and ratented Jan. 12, 190a.-

Dis-

iirroundingthe fan de and fits over the cage M. Preferably this opening is surrounded by the vertical wall of wire netting N as shown in big. 1.

7 as shown at n, and there attached in any suitable manner. It should be heavy and rigid enough to prevent the basket from sagging or getting out of shape when lifted.

in order to clearly show the rotating blades and other connected parts, these blades, the cage M and the handle 0 have been shown larger in proportion to the tank and basket than they would be in practice.

In order to supply hot or cold water to the tanks, I provide the pipe I which connects the several tanks to any suitable source of water supply, the pipe P of course having connections I provided with suitable valves leading into each tank. In some cases also it is desirable to introduce live steam into the tanks and to this end I provide the pipe Q which extends from the steam pipe I and is provided with connections to each of the tanks and with valves whereby the steam may be directed into any one of the tanks separately from the others, or be cut oil entirely as by the valve g.

The tanks are intended to be filled with water upon which grease will accumulate and hence I provide the grease pipe R. which has openings 1' into each tank at about the water level and extends downward and connects with a general waste pipe S. This pipe has connections 8 leading into the bottom of each of the tanks. This waste pipe is liable at times to become clogged, and in order to blow out the clogging matter, I pro;

vide the steam pipe I which either connects directly with the pipe I or connects to the exhaust pipe I", a suitable valve bein provided for cutting 011' the pipe I or or allowing steam to enter therein, or be forced into the pipe S. In order to create a pressure of steam within the pipe S suificient to clear out the clogged material, I form a nozzle on the pipe 1 where it enters the pipe S.

The operation of my device is as follows:-

Dishes are placed in the basket and the basket first placed in the tank A. The water therein will be carried downward by the screw-blades F, forced outward towards the sides of the tank, then upward and then over the top of the partitions L, or through the openings 1' into contact with the dishes. After the dishes have been suificiently washed in the tank A, the basket is lifted.

and placed in tank B where the water moves in a reverse direction to that in tank A. After thorough washing in the two tanks,

the basket of dishes is placed in the rinsing tank C which is simply filled with clean hot water.

The articular advantages of my invention reside in the fact that the motor is attached to and forms part of the tanks themselves, and that the exhaust steam from one tank motor is used either for driving the agitating shafts of the next tank, or injected into the tanks or into the waste pipe to clear the same.

Another advantage 1 have found to lie in the manner in which the water is circulated around the dishes and through the basket. This is due to the arrangement of deflecting and partition plates, as well as to the peculiar construction of the basket which permits the free influx and efliux of water around the dishes.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: 1

In a dish-washing machine, a tank, a shaft projecting up through the bottom of said tank, a steam motor carried on the end of said shaft for rotating the same, blades carried by said shaft just above the bottom of the tank and adapted to force the water outward to the sides of the tank, blades on the upper portion of the shaft adapted to force the water downward towards the first named blades, a cage surrounding said uppermost blades and a perforated basket adapted to be set over said cage and to contain dishes.
